Don't know about that. It seems multiples of 8mhz are fine, but not in between.It also happens with v3.9.1, and it doesn't happen with the BIG demo, for example.Needs more investigations but it's no bug specific to the alternative YM emu.

I looked at it and it's an old problem in Steem, not SSE-specific.MFP prescales (4, 10...) are multiplied by new speed/8mhz with rounding when CPU is boosted, so it gets very imprecise except when it's 2* (16mhz), 3*, etc.It's been fixed, thx for the report.

two things sound in my slide program is still wrong, the envelope is still mess up.and after you change the other thing my sound routine play to slow,

i have found out why, 2 raster line before it hits overscan i pause TimerA so it not interfere with the overscan, and let it continue after, if i removed the pause, it play in normal speed. but sometime mess up the overscanit work perfectly before and also on real hardware.the envelope also work before the last version.

i am really sorry to cause all these problems.

Hi It is me again good news now the speed is correct bad new now the sound mess up over 40mhz. there are also still error with the sound chip envelope where it either play an octave to high or remove the sound. but it not so often anymore and it is harder to trigger.

Above 40mhz, I noticed it made Steem hang in previous versions. While debugging the previous bug I inserted another bug. But normally, it only had effect above 8mhz.Do you have envelope error at 8mhz? (please try the new beta...)

Hiusing latest 3.9.2 boiler version for windows 32 bit, I can't manage to output cpu trace in the log file : by default all componenents are selected in log and log2 menus, except cpu. But each time I click on cpu and click "run" from the boiler window, then "cpu" log is automatically unselected and the resulting log file never has any cpu traces (it just has log for video, sound, blitter, fdc, ...)

I known that it used to work in some previous version, but I can't say when it stopped working.Or is there a specific action to do to have cpu traces in the log file ?

EDIT : it seems cpu traces might go into TRACE.txt and not steem.log ? But that's not very handy to see interactions between cpu and rest of the HW.
